Steinism is the political beliefs of the American physician, Jill Stein, the presidential candidate for the Green Party of the United States in 2012 and 2016.
Steinism believes capitalism tends to accumulate wealth in the hands of a few which destroys the free market and also destroys democracy. Steinism supports economic democracy "which is the parallel of political democracy", and she supports small government, local decision-making with regional coordination and guidelines.
